android run time permission handler

RunTime Permissions

This Android library provides Kotlin extension functions that make run time permission handling easier and more concise. These extensions provide same implementation for permission handling in both Activities and Fragments.

Usage

Most of the system permission are defined in AppPermission.kt class.

Add it in your root build.gradle at the end of repositories:

	allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}

Add the gradle dependency to your app module build.gradle file:

	dependencies {
	        implementation 'com.github.ajithvgiri:runtimepermission:v1.1'
	}

Don't forget to add permissions in Manifest

Single Permission

    companion object {
        private const val PERMISSION_REQUEST_CAMERA = 100
    }

    // Single Permission
    private fun askPermission(permission: String = PERMISSION_CAMERA, requestCode: Int = PERMISSION_REQUEST_CAMERA) {
        checkRTPermission(permission) { result ->
            when (result) {
                CheckPermissionResult.PermissionGranted -> {
                    showMessage("Permission Granted")
                }
                CheckPermissionResult.PermissionAsk -> {
                    ActivityCompat.requestPermissions(this, arrayOf(PERMISSION_CAMERA), requestCode)
                }
                CheckPermissionResult.PermissionPreviouslyDenied -> {
                    // Show some message for user why this permission is needed
                    ActivityCompat.requestPermissions(this, arrayOf(PERMISSION_CAMERA), requestCode)
                }
                CheckPermissionResult.PermissionPermanentlyDenied -> {
                    // Show action for navigating user to settings 
                }
            }
        }
    }


    //Permission Request Result
    override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<String>, grantResults: IntArray) {
        when (requestCode) {

                val cameraPermissionAccepted =
                    grantResults[0] == PackageManager.PERMISSION_GRANTED

                    showMessage("Camera Permission Enabled")
                } else {
                    showMessage("Camera Permission Denied")
                }
            }
        }

    }


    // Multiple Permissions
    buttonContactPermission.setOnClickListener {
        val contactReadWritePermissions =
            arrayOf(PERMISSION_READ_CONTACTS, PERMISSION_WRITE_CONTACTS)
        askPermissions(contactReadWritePermissions, PERMISSION_REQUEST_CONTACT)
    }

    buttonStoragePermission.setOnClickListener {
        val externalStorageReadWritePermissions = arrayOf(PERMISSION_READ_EXTERNAL_STORAGE, PERMISSION_WRITE_EXTERNAL_STORAGE)

            PERMISSION_WRITE_EXTERNAL_STORAGE
        )
